Summary:
A REVISED BRAKE LINING NOISE INSULATOR RESULTED IN A DECREASE IN THE THERMAL INSULATION BETWEEN THE BRAKE LINING AND THE FRONT BRAKE CALIPER PISTON. THIS CAUSED GREATER HEAT TRANSFER TO THE CALIPER PISTONS WITH THE POTENTIAL TO OVERHEAT THE BRAKE FLUID AND DIMINISH BRAKE EFFECTIVENESS DURING SEVERE BRAKING CONDITIONS. |
||
|
Consequence:
INCREASED STOPPING DISTANCES AND INABLILITY TO HOLDVEHICLES ON A STEEP GRADE RESULTS IN INCREASED RISK OF ACCIDENT IN THE EVENT OFA SUDDEN STOP OR WHEN CONSTANT BRAKING IS NEEDED TO MANEUVER THROUGH AREAS WITHSTEEP GRADES. |
||
|
Remedy:
ADD SNAP-IN INSULATORS THAT ATTACH TO EACH OF THE FRONT BRAKE CALIPER PISTONS. IN ADDITION, VEHICLES WITH 7.5 L ENGINES WILL HAVE INSULATION ADDED TO THE ENGINE COMPARTMENT BRAKE LINES. |
